In the episode, Arthur, Francine, Buster, and Muffy discover their third-grade teacher, Mr. Ratburn, is engaged. But the animal friends are surprised to discover that on the day of the wedding, Mr. Ratburn walks down the aisle arm in arm with his partner, Patrick, a local chocolatier. As the two animated creatures walk down the aisle, all guests smile in celebration of the same-sex marriage. Afterward, the students eat cake, which was shown earlier in the episode with two toppers that resemble Mr. Ratburn and Patrick.
